The Great Wall has been evolving almost since FuzzHugger(fx) began...its evolution continued with the limited run of Fuzz Hugers (40 made). Everything learned from its previous iterations has brought us to this.
NEW FEATURES:
• Radio-frequency protection.
• New Mode Toggle with diode switching.
• Bypassable Bass and Treble controls with built-in diode switching.
• New clipping arrangement in Tone-On Mode.
• New MIDS Toggle for Tone circuit--scooped or boosted mids!
• No more volume drop with Tone engaged!
CONTROLS:
• Push - Gain & fuzz. The last turn of the Push knob adds compression and a more pronounced texture/fuzz. Functions differently with both Diode Toggle modes.
• Diode Toggle - Switch between silicon and LED clipping, standard or a hotter-yet-clearer mode. (Works with Tone controls on or off.)
• Tone Toggle - Activates Bass/Treble/Mids controls, and simultaneously switches the second diode stage for a change in tone and more headroom.
• Treble
• Bass
• Mids Toggle - Down = scooped mids, Up = more mids.
• Level - Level.
Very small numbers IN STOCK at Prymaxe Vintage in NJ!
Demo coming shortly. Imagine the Great Wall / Huger on steroids.
Oh no. and I just bought the "last" great wall from Prymaxe.
I'm not complaining. I'm very happy with my great wall. And the new ones look damn good! I may just have to get another! Can't wait for the demo, I'm expecting a monster.
